Command	What does it do?
git init	Create empty Git repo in specified directory. Run with no arguments to initialize the current directory as a git repository
git clone <repo>	Clone repo located at <repo> onto local machine. Original repo can be located on the local filesystem or on a remote machine via HTTP or SSH.
git config user.name <name>	Define author name to be used for all commits in current repo. Devs commonly use –global flag to set config options for current user.
git add <directory>	Stage all changes in <directory> for the next commit. Replace <directory> with a <file> to change a specific file.
git commit -m “<message>”	Commit the staged snapshot, but instead of launching a text editor, use <message> as the commit message.
git status	List which files are staged, unstaged, and untracked.
git log	Display the entire commit history using the default format. For customization see additional options.
git diff	Show unstaged changes between your index and working directory

Rewriting History

Command	What does it do?
git commit –amend	Replace the last commit with the staged changes and last commit combined. Use with nothing staged to edit the last commit’s message
git rebase <base>	Rebase the current branch onto <base>. <base> can be a commit ID, branch name, a tag, or a relative reference to HEAD.
git reflog	Show a log of changes to the local repository’s HEAD. Add –relative-date flag to show date info or –all to show all refs.

Undoing Changes

Command	What does it do?
git revert <commit>	Create new commit that undoes all of the changes made in <commit>, then apply it to the current branch.
git reset <file>	Remove <file> from the staging area, but leave the working directory unchanged. This unstages a file without overwriting any changes.
git clean -n	Shows which files would be removed from working directory. Use the -f flag in place of the -n flag to execute the clean.

Git Branches

Command	What does it do?
git branch	List all of the branches in your repo. Add a <branch> argument to create a new branch with the name <branch>.
git checkout -b <branch>	Create and check out a new branch named <branch>. Drop the -b flag to checkout an existing branch.
git merge <branch>	Merge <branch> into the current branch

Remote Repositories

git remote add <name> <url>	Create a new connection to a remote repo. After adding a remote, you can use <name> as a shortcut for <url> in other commands.
git fetch <remote> <branch>	Fetch the specified remote’s copy of current branch and immediately merge it into the local copy.
git pull <remote>	Fetch the specified remote’s copy of current branch and immediately merge it into the local copy.
